# What are the ideal operating temperatures of both ceramic PCB and MCPCB?

_Published: 2016-08-12_

Normally working temperature of MCPCB is <130â„ƒ, better less than 100C, dielectric layer in MCPCB is the bottle neck for high temperature, as the Tg value of that layer is only 130â„ƒ

Ceramic PCB can be: -50â„ƒ to 800â„ƒ.

So if temperature higher than 130â„ƒ, then Ceramic PCB or High Tg PCB (but only around 170C) is good choice.
